A very common failure of the 7.3L fuel system, especially when changing out injectors is the injectors cups, also known as an injector sleeve. These cups are prone to cracking, causing a leak down, which can simulate bad injectors. Even if your existing cups aren't damaged, we would highly recommend replacing them when changing your injectors for peace of mind there are no seating issues.
